Translation issues make it difficult to extract details. Mobily sent out its tweet on March 25, but the translated web page mentions a Saturday, March 30 date.

Mobily is the first operator in KSA delivering HD voice. The service will be provided to both prepaid and postpaid customers at no additional charge.

The Middle East and Asia continue to deploy HD voice at a steady pace, leaving the Americas relatively barren with the exception of Canada (All major carriers), the Dominican Republican (A France Telecom/Orange subsidiary) and T-Mobile USA offering the service.
